I have half a recollection of Wyll swearing by �the triad�, who according to my reading of the FR wiki, are Torm, Tyr and Ilmater. I think there�s a comment he makes after one of the stages in Gale�s personal quest where he compares Gale�s devotion to Mystra to his less pious viewpoint. Perhaps someone who knows more about the Faerunian pantheon has a more definite recollection.
True, but Wyll aside from swearing by the Triad also swears by Helm, and his father mentions Helm multiple times. So, again, quite hard to pinpoint! Hence this topic!
